PLUMB, LEVEL, AND SQUARE.

Application filed July 22, 1916.

To all whom z'zfmay concern:

Be it known that we, Josrrrr E. GAeNoN, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,J GEN A. HAWTHORNE, J11, a citizen of the United States, residing atChester, in the countyof'Dela-w-are, State of Pennsylvania, haveinvented a new and useful Plumb, Level, and Square, of which thefollowing is a specification.

Our invention consists of an implement or device which is adapted to beconverted into a plumb, a level, a square, and an inclinometer, andforms various kinds of squares as a try square, T-square, miter, etc.,the novel features being set forth in the claims that follow thespecification y The invention is satisfactorily illustrated in theaccompanying drawing, but the important instrumentali-ties thereof maybe varied, as long as they are included in the scope of the claims.

Figures 1, 2, 3 and 4 represent side elevatlons of a device embodying aplumb,

level and square, embodying our invention, the members thereof being indifferent positions in the several figures. I

Fig. 5 represents a longitudinal section on the line w ac Fig. 2.

Fig. 6 represents a transverse section of a portion on the line g y Fig.2.

4 ig. 7 represents a side elevation of a portion of a modification.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring" to the drawings.

1 designates a graduated blade in which is the longitudinally-extendingslot 2, the latter receiving at one end the screw 3, the head 4: whereofoverlaps the walls of said slot, and the shank whereof enters a threadedopening eccentric in the disk 5 in which are lips 6 turned-out from thesame and engaging the adjacent edge of the blade 1, thus firmlyconnecting said disk with said blade.

7 designates a stock which carries the easing of a spirit-bubble 8firmly secured thereto in any suitable manner, adapting the stock toform a spirit-level as in Figs. 1, 2 and 3.

In one side of what may be termed the Specification of Letters Patent.

Patented Feb. 13, 1917. Serial No. 110,662. b

head of the stock which is formed of double walls is the circularopening 9, the wall whereof is freely mounted on the circular disk 5,whereby said stock may be rotated on the latter and so change its anglewith respect to the blade 1.

On. the end of the screw 3 opposite to the head 4 isthe thumb nut 10,whereby the stock 7 may be which it may be placed on the blade 1, it

s the stock. may be placed at the end of the lads, at the centerthereof, or intermediate of its ends, so as to form a try or T-square, amiter, and other kinds of squares, and a protractor as desired, someforms of which are shown in the different figures.

In the stock 7 is the longitudinally-extending slot or recess 11, inwhich the blade may be received or folded in. some of the positions inwhich the blade and stock be placed, see Figs. 1 and 5.

The other side of the is cut screw 3 which head 4: projects into said'recess, and said bar 14 receives the shank of the screw 15 which entersa threaded opening in the center of the disk 5 and carries the thumb nut16 which is adapted to tighten the stock on said disk in the position inwhich either said stock or the blade may be placed with relation to eachother.

It is evidentthat vice may be manlpulated to form a plumb orinclinometer of the latter, or convert it into a spirit level, differentkinds of squares, a rule, or measure, the latter being due to thegraduated blade 1.

Owing to the graduations on the disk 5,

on, relatively to the desired angle of the latter, so as to be easilyread ofi".

The end of terminal of that b the stock 7 to the full extent of saidslot one of the lips 6 may clear said end of the blade and permit thestock to make a full turn on the disk with the screw 15 as its centerand tightened in the position in may the members of the de connectionfor thus change the position of the stock from that shown in Fig. 2 tothat shown in Fig. t for purposes requiring the same.

In Fig. 7 we show pins 18 inserted in the disk 5, the same being adaptedto abut against the adjacent edge of the blade 1 in lieu of the integrallips G, and operate in connection with the screw 3 to retain said diskon said blade.

The entire device may be formed of metal which renders it strong,durable, light and comparatively inexpensive.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent, is

1. A blade, a stock, a circular member on said blade, the head of saidstock being rotatively mounted on said member, a central connection forsaid blade and member, and a stop on said blade adapted to engage a wallof said head to limit the rotation of said stock.

2. A blade, a stock, a circular member on said blade, the head of saidstock being rotatively mounted on said member, a central said stock andmember, a threaded member extended axially through said circular member,and means on sai circular member and blade adapted to connect the lattermember and blade.

3. A blade, a stock, said blade, the head of said stock being r0-tatively mounted on said member, a central connection for said stock andmember, a threaded member extended axially through said circular member,means on said circular member and blade adapted to connect the lattermember and blade, and means for tightening said threaded member.

l. A blade having a longitudinally-extending slot therein, a stock, acircular member on said blade, the head of said stock being rotativelymounted on said circular member, a central connection for said blade,and a threaded member adapted to'"*pass through said slot and engagewith the walls thereof to enter said circular member eccen- Gopies ofthis patent may be obtained for five cents each,

a circular member on trically in an opening therein, and means fortightening said threaded member in position.

5. A blade having a longitudinally-extending slot therein, a stock, acircular member on said blade, the head of said stock being rotativelymounted on said circular member, a central connection for said blade, athreaded member adapted to pass through said slotrand engage with thewalls thereof and to enter said circular member eccentrically, and a lipon said member adapted to engage the edge of said blade opposite to saidthreaded member thereby connecting said blade and circular member.

6. A blade, a stock having in its head a recess forming a diametricalbar, a circular member on said blade, said stool: being rotativelymounted on said member, means for centrally connecting said member withsaid bar, a threaded member for eccentrically connecting said circularmember with said blade, said threaded member being secured to said bladeand having its head freely enter said recess and adapted to limit therotation of said stock.

7. In a device of the character stated, a blade, a stock, a blade, adevice for adjustably colmecting said stock with said blade, means forpivotally mounting said stock on said circular member, said stock havinga head formed of a plurality of walls, between which portions of saidblade are movable slidingly and rotatably, one of said walls beingrotatively mounted on said circular member, the other wall havingtherein a recess adapted to receive freely the head of the device thatconnects said stock with said blade as a stop for limitingthe rotationof said stock in its opposite directions on said blade.
